i have it set to metric, what im trying to do, is i have my pilots flying thru a canyon, i want to keep them below 300 AGL...if they break it..it spawns an alert flight i have tied to the zone.
I just played with moving the point next to the runway, not on it but a little ways out ..i set the alt for 100 which should be 300 ft. however sitting on the runway triggered it. my ALT sitting on the run way is 1200 ..so im not sure its going off of AGL
